Deep loosening
An agricultural practice of loosening the soil at a significant depth without inverting the furrow slice to break up compacted layers and improve soil structure.

The primary purpose of deep loosening is to break the plow pan, a compacted layer that restricts root penetration and impairs water infiltration. By shattering this dense zone, farmers can enhance subsoil aeration and allow moisture to penetrate deeper into the profile.
This operation is typically performed in autumn when the soil is at an appropriate moisture level to ensure effective fracturing rather than shearing. Performing deep loosening when the soil is too wet is a major error, as it can cause soil smearing and compaction, which negates the intended benefits.
Common mistakes include operating at an incorrect depth that fails to reach the compacted layer or failing to adjust the working speed, which can lead to uneven soil disturbance and increased fuel consumption.
